Abstract

A dynamic assessment system for monitoring high-voltage electrical components, which includes a computer system that is configured to receive data from a plurality of on-line sensors configured to monitor various operating parameters associated with the operation of a plurality of electrical components such as a plurality of electrical transformers. The computer system is configured to automatically and continuously correlate the data from the on-line sensors with data from various off-line databases and supervisory networks associated with monitoring the operation of the power distribution network, so as to generate dynamic operating condition assessments, including risk of failure assessments, of each of the monitored electrical components.

First claim

What is claimed is:

1. A dynamic assessment system for monitoring high-voltage electrical components comprising:
at least one on-line sensor that is coupled to one or more on-line electrical components operating with a load, said on-line sensors configured to monitor and collect on-line operating parameter data associated with the operation of the one or more on-line electrical components;
at least one off-line database adapted to store off-line operating parameter data associated with the operation of the one or more on-line electrical components that is taken off-line, wherein said off-line operating parameter data represents off-line testing of said one or more on-line electrical components that is taken off-line and wherein said off-line operating parameter data, is acquired when said one or more on-line electrical components are de-energized for off-line testing;
at least one off-line data storage system adapted to store historical off-line operating parameter data associated with the maintenance, testing, and operating performance of the one or more on-line electrical components;
a supervisory control and data acquisition (SCADA) network to receive SCADA data associated with the one or more electrical components associated with said SCADA network; and
a computer system coupled to the one or more on-line electrical components and to the one or more on-line electrical components taken off-line, the computer system in operative communication with said at least one on-line sensor, said at least one off-line database, said at least one off-line data storage system, and said SCADA network with respective data communication interfaces, wherein said on-line operating parameter data from said at least one on-line sensor and said off-line operating parameter data from said at least one off-line database are each received at said computer system through different interface models associated with respective ones of the on-line and off-line electrical components, said computer system configured to automatically and continuously correlate output from said interface models with said historical off-line operating parameter data and said SCADA data,
wherein said computer system generates a course of action that is associated with each of the one or more online electrical components, and said course of action includes reducing the load of the one or more on-line electrical components based on said correlated output from said interface models, said historical off-line operating parameter data, and said SCADA data,

4. The dynamic assessment system of claim 1 , wherein said computer system is configured to generate an interactive interface that is configured to be remotely accessible by a remote computer system.

5. The dynamic assessment system of claim 1 , wherein said dynamic operating assessment is selected from the group consisting of risk of failure, overload capability, aging factor, and cumulated aging time.

6. The dynamic assessment system of claim 1 , wherein said computer system uses artificial intelligence to generate said recommended course of action.

7. The dynamic assessment system of claim 1 , wherein said computer system is configured to be hardware independent of said on-line sensors.

8. The dynamic assessment system of claim 1 , further comprising a display in operative communication to said computer system to display said recommended course of action or said dynamic operating assessment.

9. A method of assessing at least one high-voltage electrical component comprising:
providing a computer system;
providing at least one on-line sensor in operative communication with said computer system that is interfaced to at least one on-line electrical component to monitor and collect on-line operating parameter data;
providing at least one off-line database in operative communication with said computer system, said off-line database representing the off-line operating, parameter data of at least one on-line electrical component that is taken off-line;
providing at least one off-line data storage system in operative communication with said computer system, said off-line data storage system representing historical off-line operating parameter data associated with the maintenance, testing, and operating performance of said at least one on-line electrical component;
providing a supervisory control and data acquisition (SCADA) network to receive SCADA data associated with the at least one on-line electrical component associated with the SCADA network;
acquiring the on-line operating parameter data, the off-line operating parameter data, the historical off-line operating parameter data, and the SCADA data at said computer system, wherein said computer system is coupled to said at least one on-line electrical component and said at least one on-line electrical component taken off-line and the off-line operating parameter data is acquired when the at least one on-line electrical component is taken off-line and de-energized, and wherein the on-line operating parameter data and the off-line operating parameter data are each acquired through different interface models of the computer system associated with respective ones of the on-line and off-line electrical components;
